HP defends intellectual property rights

9 November 2006 — Berlin (GER): Hewlett-Packard (HP) has filed a formal complaint against the German subsidiary of Korean-based InkTec, for violation of HP patents for ink formulations.

Inks contained in the InkTec-branded "do-it-yourself" refill cartridge kits are claimed to violate HP ink patents. To protect these patents, HP has filed the complaint through the court system in Germany where the InkTec inks were found.


The discovery of the challenged InkTec inks is the result of ongoing worldwide testing and enforcement efforts within the Supplies unit of HP’s Imaging and Printing Group.
